Application filed December 24, 1924. Serial No. 757,858.

Our present invention has reference to a conveyor for binding mach nes.

Our ob ect is to dispense with the fabric conveyors and elevators for binding machines and employ inlieu thereof endless chains supported in a manner whereby the straw and grain will be positively delivered from the platform on to the elevator with out loss, and whereby the wedging and jamming ofthe' stalks of straw at the juncture of the respective conveymg and elevating mechanisms will be entirely overcome.

A further object is theprovisionfof a conveyor for binding machines comprising endless chains having spaced fingersthereon for gripping the straw, the upper leads of the said chains being trained through grooves in metallic aprons.

A still further object-Ts, the. provision of a conveyor for binding machines which will obviate the necessityoftaking up the slack in either the conveyor or the elevator, which is of a construction to render the same strong and durable so that the life thereof, with respect to that of the ordinary conveyor, is greatly increased, and wherein Y the upper elevator or packer is adjustable with respect to the lower elevator so that heavy or light loads of straw may be conveyed with equal efliciency. I

To the attainment of the foregoing broadly stated objects and many others which will present themselves as the nature of the invention is better understood, reference is to be had to the drawings which accompany and which form part of this application.

In the drawings Figure 1 is a side elevation of the im provement in applied position, a part of the binder frame and the floor of the conveyor platform being in section;

Figure 2 is a top plan View.

Figure 3 is a sectional view on the line 33 of Figure 1.

Figure 4 is a sectional view on the line H of Figure 1.

In the embodiment of our improvement illustrated by the drawings, a portion of the binder frame is indicated by the numeral 1. Secured to the frame in any desired manner there is the substantially rectangular casing 2 of the improvement. The cas ing is preferably of metal and has journaled in bearings, adjacent to its ends, shafts 3 and 4, the said shafts having keyed thereon the lower elevator. trained around an upper sprocket wheel 17 sprocket wheels 5 and 6 around whic'hlthere 1 of the chains'areprovided with outstanding lingers 8' and the fingers on therespective' chains are inalignment.

J ournaled in suitable hearings on the base" 9 of the cas ng 2 there are spaced wheel! 10 arranged in pairs and connected together by pins 11. The wheels or rollers-contact with the'under faces of the lower lead of the chain conveyor 7, while the spaced connectin'g pins therebetween permit of the passage of the flights or fingers8 between the said rollers. The rollers prevent the sagging of'the lower lead oft-he conveyor. I

The casing, between .thetoothed wheels 5 and 6, has a fiat top 12, and this topis formed with spaced longitudinal depressions providing channels 13 for the upper leads are trained the endless chains 7 thatco'n stitute the conveyor. Certain of the links ofthe chain conveyor 7. The depth of the j channels equals the thickness of the chain links'and thewidth 'of'the channels correspond to the width of'the said chain links. In this manner it will be seen that the upper leads of the said endless chains are effectively guided over the top of the casing and that grain from the straw arranged on the conveyor cannot drop into the channels.

, Keyed on the shaft 4 there are spaced rollers 14 of a larger size than the toothed or sprocket wheels 6; Each sprocket wheel is arranged between two of the rollers 14, and keyed on the shaft between the adjacent pair of rollers to those just mentioned there are sprocket wheels 15. These sprocket wheels are of a less diameter than the sprocket wheels 6 and have trained therearound the endless chain 16 that provides The chain 16 is also supported on the usual angle bar connected with one of the uprights of the binder frame. The upper leads of the lower elevator chains 16 travel through channels 18 in metal plates or aprons 19 secured between the rollers 14 and the sprocket chains 17.

Theangle bar 20 on which the shaft 21 for the sprocket wheels 17 is journaled, is extended upwardly a considerable distance beyond the said sprocket wheels 17 and has secured thereto rightangularly disposed upwardly directed arms 22 provided with slots 23. 'The upright 24 to which the angle member 20 is secured is also provided with received in the slots of the armsthere are bearings for shafts 27' that have keyed thereon sprocket wheels 2828 around. which are trained the endless chains 29 that provide the upper or packer elevator. Both of the elevators have their chains provided with outstanding fingers or flights 30 respectively, and the fingers on the respective elevators are disposed in parallelism. Suitable means, such as the rollers 10 and the fingers 11 may be provided for preventing the inactive leads of the chain conveyors from sagging'and of course, suitable means is provided for adjusting the hearings for the shafts 27. By such arrangement either wet or dry straw may be fed with equal efficiency between the elevators 16 and 29.

The operation of our improvement will, it is thought, be apparent to those skilled in the art to which such inventions relate. The straw delivered on to the conveyor 18 is directed thence on to the rollers 14, which, being of a greater diameter than the toothed wheels 6' but rotating at the same angular velocity as the latter, have a greater peripheral speed than the linear speed of the conveyor 7. But these rollers are positioned at the throat defined at the juncture of the horizontal conveyor 7 and the elevator 16 and exceeding, as aforesaid, the linear speed of the conveyor, the straw immediately upon same, and means disposed in said throat for unobstructed contact with the product being conveyed to accelerate the speed of said product at the time of its transfer from the horizontal conveyor to the elevator, both of said conveyors comprising each a plurality of chains arranged in parallelism and hav ing sprocket wheels over which they are trained, a shaft positioned in the region of said throat and carrying the sprocket Wheels at the adjoining ends of said conveyors, and

said means comprising rollers carried on said shaft and arranged in intercurrent rela tion with the chains ofsaid conveyors, said rollers being appreciably larger in diameter than the diameters of said sprocket wheels and being slightly less in width than the width of the space "between the chains.

In testimony whereof WQ'ZLlfiX oursigna- JOHN N. STOUT. EARL" SGHLEGEL.
